Default DDE Missing DPF Rheingold Guru Needed

I have been having an intermittent issue with apparent lack of turbo boost on my car an E65 2004 730D Sport, when the fault is not present the turbo kicks in and the engine pulls as expected.

Usually the first journey of the day, regardless of distance. once switched off and sat for a while the car seems sluggish and the turbo doesn't kick in like it should.

I have ran a vehicle check and the following faults are present...

4203 Glow Control Unit
4503 Charge Air Pressure Control
4507 Exhaust Gas Recirculation



I have read elsewhere that the DPF is a big cause of lack of power, but don't have any apparent errors related to it.

When I try and check on the DPF there doesnt appear to be any reference to it anywhere within the DDE module..

The DDE module provides readings as per thumbnail,



When I try and run the Service Function to regenerate the DPF there is only one Diesel Electronics Option, which doesn't contain any reference to the DPF. I'm aware the glow control unit may prevent a DPF regen.





Can anyone suggest whats going on ? I'm pretty sure the DPF has never been removed....How would I check apart form visually....?

If I use the VIN number to identify the car, I get 2 Diesel Electronics options, and the DPF is mentioned....

Hello!

Your car is not factory equipped with DPF so that's not your problem.

I'd check the vaccum supply for the turbocharger (a.png)
- usually a leaky hose or the converter are the issue

Also check the vaccum for the EGR system (b.jpg)
- usually a leaky hose or the converter are the issue

Are you sure about there being no DPF ?
I plan to check the EGR to check it's working correctly ?

three ways to check what i'm telling you

1. put your finger inside the tailpipe, if comes out bleck as hell then you don't have a dpf
2. access etk and try to identify the dpf for your vehicle (you won't find any)
3. check the right side of the engine. in case you have a dpf, there would be a hose coming from the exhaust and connecting to a sensor (the differential pressure sensor)

I was under the impression that the DPF was integrated into the catalytic convertor on pre facelift E65s and became a seperate unit post facelift.

Yep very black thumb

I've removed and cleaned the EGR valve and confirmed the plunger operates.
The blue / black vacumm pipe doesn't appear to have a lot of suction if any at all.
Where's the other end attached ?
